netfilter: xt_hashlimit: fix race between htable_destroy and htable_gc
Deleting a timer with del_timer doesn't guarantee, that the timer function is not running at the moment of deletion. Thus in the xt_hashlimit case we can get into a ticklish situation when the htable_gc rearms the timer back and we'll actually delete an entry with a pending timer. Fix it with using del_timer_sync(). AFAIK del_timer_sync checks for the timer to be pending by itself, so I remove the check.
